Problem WRT54G-EU v2.2 whith HyperWRT

The problem is don't have any response from the router. The power led is flashing, DNZ and WLAN off.

There is a bug? My mistake was the next process;
- When I flash the HyerWRT all was right..........
- Start telnet on web config.
- Connect "telnet 192...........
- #nvram set clkfreq=220
#nvram commit
#reboot
And now, the router is waiting a new flash (power led flashing)???????

Have I anyway for flash my router? I used tfpf few days ago with other firmwares and any problem, but now the tfpt don't connect..... maybe when I flash with this firmware "boot_wait" was turned "off"?
